Recently, Flickr introduced its short URL service for all photos (and videos) hosted on Flickr. All photos and videos have a corresponding flic.kr URL associated with them, in the format of flic.kr/p/xxxxxx (the last part is the base-58 encoding of the photo-id)
If flickr was using base58 on its servers in 2007 it should show up in short links in the source code of pages archived back then, but it doesn't.
The image on this page was archived in 2007, then again in 2009.
A shortened link to it containing base58 doesn't show in the December 2007 snapshot of it, but does in the 2009 snapshot. Search the source code of these two snapshots for flic.kr/p/ yourself. It only appears in the 2009 snapshot.
